Official description

countly-server is the server-side part of Countly, a product analytics solution. Prior to versions 22.03.7 and 21.11.4, a malicious actor who knows an account email address/username and full name specified in the database is capable of guessing the password reset token. The actor may use this information to reset the password and take over the account. The problem has been patched in Countly Server version 22.03.7 for servers using the new user interface and in 21.11.4 for servers using the old user interface.

The underlying weakness: Weak Password Recovery Mechanism for Forgotten Password

The product contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.

How developers prevent this class of flaw

  • Make sure that all input supplied by the user to the password recovery mechanism is thoroughly filtered and validated.
  • Do not use standard weak security questions and use several security questions.
  • Make sure that there is throttling on the number of incorrect answers to a security question. Disable the password recovery functionality after a certain (small) number of incorrect guesses.
